Findlay Street - Dayton, Ohio. | 1.2 Details of the Gamma Room construction are shown i in the drawing of page !!7 The original room (Gamma Room #1) was constructed with 32" solid concrete walls. Gamma Room J2 was constructed ;

, ! with c minimum of 24" solid concrete blocks. ' IE The entire facility is constructed on the ground level and no below ground area is accessible ! ]E within the restricted area including manholes 4 |g or other sources of ingress such as sewers, con- jg duits, or natural voids such as caves or tunnels. i | j Note: Gamma Room #2 uses only a collimated source. | j 1.3 The roof over the gamma rcoms is fenced to prevent | accidental entry to this area. The area is also j | marked by the appropriate " CAUTION - HIGli RADIATION AREA" signs. The roof is not constructed as a radiation barrier and as mentioned is a high radia- For this tion area when the sources are exposed. . reason no survey is made beyond Area "P", the fence | indicating the 2 MR/IIR limit. To do so would subject the radiographer making the survey to unneces- ' :ary radiation exposure. ! | | 1.4 A typical survey of the radiographic facility as i shown on page 7 of this application and as Appen-

1.4.17 Area Q - (Top of ladder at south end of N.D.E. Laboratory) 1.5 MR/IIR 1.4.17.1 Beyond the barrier at the top of the roof access ladder the radiation levels vary between 6 MR/HR and 10 MR/IIR. Ingress to the roof of the N.D.E. Laboratory is only permitted when clearance has been obtained from the radiographer in charge and radiography will not be conducted until after the roof has been vacated and found to be secure.

!:o t e : The multiple readings are at the surface and at 18 inches from the areas indicated and may vary somewhat due to source strength when the survey is taken. No reading over 2 MR/IIR is anti.- cipated and the previous survey readings are available for com- parison when the survey is made. In addition to the above, each ;;arma room is equipped with the following safety devices - 2. Safety Devices:

2.1 A Nuclear Measurements Corporation Model GA-2T I G;nrma Alarm which is set to activate an audible alarm anytime the radiation level in a room reaches 2 mr/hr and the access door is open.

2.2 Blue at robe ligl.ts are mounted over each exposure device. These lights are activated by any radiation ovm ? nr/hr at t. b e sensor: f o r t h e (; A- 2 T ",a mma a l a t . .'

: 2.4 over each access door to the gamma rooms are loca- | ted two (2) red lights. When lighted, these indicate the crank does not show the source to be in j a safe position. | i 2.5 Also, over each access door are two (2) yellow I ; lights that when lighted indicate the access door | is not closed. An unsafe condition does not neces- I. sarily exist.

; 2.6 To gain access to either gamma room, a key lock i must be activated; however, no key is necessary ; to exit either room.

9 { These keys are restricted to Radiographers, Radio- ! grapher's Assistants, and the Radiation Safety Officer. t I 2.7 Both Gamma Room access doors are clearly marked

., with " CAUTION - HIGH RADIATION AREA" signs,

, " CAUTION - RADIATION AREA" signs, and " CAUTION i - RADIOACTIVE MATERI AL" signs .

; 3. Equipment Position: | | ' 3.1 The area in which the Radiographer must stand to operate the crank is located as far from the source a r, ; possible. In this position, he is protected , i from radiation by the maze and is within arms reach | of the access door, j ' 3.2 A working; area is identified in Gamma Room #1 and no panoramic radiography is allowed outside this I area. See drawing on page 57. 3.3 A 3/8" lead , hie ld is used over the source in Gamma Room il when panoramic radiography is used. i | 3.4 The collimator in Gamma Room #2 is stationary and ;.

no panoramic ca d i o r,ra ph v is allowed i.n t h im room. ,

! ' I Eberline Instrument Corporation Model E-130-G survey meters with ranges of 0-10, 0-100, and 0-1000 mr/hr are used in the detection of I gamma radiation. Four (4) of these units are available, one for each gamma room and two for back-up in the event I of a malfunction. The Eberline Model E-130-G is a shielded geiger type counter and will be used for radiation surveys of equipment and radiation areas. Each Radiographer or Radiographer's Assistant will have in his possession one of the above survey meters in good operating condition and within calibration dates prior to performing any radiography.

Procedure for the Receiving and Subsequent Return of Radioactive I Isotopes of Iridium 192 and Cobalt 60

1. Isotopes will be received on an as needed basis from Gamma Industries in Baton Rouge, La. 2. Actual date of delivery to Duriron will never be certain due to the many variables encountered in handling isotopes.

3. The following steps are to be followed without exception whenever a carrier delivers a radioactive isotope to the Duriron Company, Inc. Stickel, who is the , 3.1 Immediately notify Norman R. ' Deputy Radiation Safety Officer of the Duriron Company, of the arrival of an isotope. | 1 ' I 3.2 In the absence of Mr. Stickel or if he cannot be contacted, notify Billy C. Key who is the Chief Radiographer. | 3.3 Either Mr. Stickel or Mr. Key will make arrange- ments to survey the isotope prior to the unloading of said carrier. 3.4 Upon receipt of the radioactive isotope, it will be transferred to the Radiographic Laboratory

where it will be kept under lock until such a , time as it can be replaced with a new isotope.

3.4.1 Upon receipt of the radioactive iso- I top e , the Shipping Department foreman " will make available a fork truck to transfer the isotope to the Radiographic g'{ Laboratory as expeditiously as possible. - 3.5 If for some reason a radioactive isotope is received and neither Mr. Stichel nor Mr. Key can be notified, the following steps should be fol- [* ' lowed.

in an area not frequented by personnel and immediately the following day Mr. Stickel or Mr. Key must be notified.

3.5.4 It is understood that isotopes are re- ] leased for delivery on a specific date and accommodations are made to facilitate same. The above is primarily a contingency plan should the unexpected occur.

4 As soon as possible after the Radiographic Laboratory is in possession of a new isotope, the spent isotope now in use will be transferred to the shipping container and the following steps must be followed.

4.1 A miscellaneous shipper will be obtained by either Mr. Stickel or Mr. Key listing the returned cource (isotope) number, source etrength in curies, the I shipping container number and all other pertinent information needed. E | 4.2 The Traffic Manager will be notified that a spent I source or isotope is ready to be returned to the encapsulation facility in Baton Rouge, Louisiana for proper disposal. 4.3 The Traffic Manager and the Radiographic Department personnel will agree upon a shipping date and time. 4.4 The " operating instructions for source changers" that is filled out by a Radiographer will be dated and the time recorded when the source leaves the Radiographic Laboratory. 4.5 A copy of the bill of lading with "he ate of acceptance by the carrier will be i.ain;ained in the Radior,raphie Laboratory with che aaove mentioned form. 5.
